Abstract :

Increasing demand of fossile fuel there is need to study a number of renewable sources. In present investigation influence of input parameter such as injection pressure, compression ratio and load on the

performance of single cylinder diesel engine fueled with soybean biodiesel and its blend. The test are carried out with

three different injection pressure (160, 200, 240 bar), compression ratio (18, 17, 16), load (1, 6, 11) and percentage of

biodiesel (100%, 50%, 0%). This study investigated by Response Surface Methodology to optimize the performance

parameter such as Mechanical efficiency. A set of experimental runs was established by using a Central Composite

Design and the RSM was employed to obtain the regression model for the Mechanical efficiency for different values of

input parameter. The experimental results reveal that the soybean biodiesel and its blend provide better engine performance compared to diesel with little change in input parameter.
